Just my two cents here..
2. Revan did take some of the Mando's tactics, difference is he used them better, he made them better. So yes, he did outwitt them. If Revan used the exact same tactics the Mando's used again and again all the same way it would have been a short war.
3. This is one of the thing's I don't get. "Kreia lies" I hear, then "Kreia said Meetra is her best student". Um..but doesn't she...?- Ah forget it.
4. I'm still sticking with the "not at his best" thing I said before.
